TO -ALL WHOM IT MAY GONCERlbT:-

Be it known that we, EDWARD VFlfrzniauvrw and ISAAC BALL, of Portland, in the county of Multnomah, State oi' Oregon, have invented new and useful Improvements in Machines for Securing and Finishing Leather; and

' we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, made part of this specification, in which- Figure l is a perspective view. v

Figure 2 is one-hali` a vertical longitudinal section on the line :z: 1v, iig. 1, and one-half a. side elevation.

Figure 3 isla front elevation of the middle rubber, with parts of the adjoining rubbers.

Figure 4 is a detached plan of the catches for restraining the levers.

In the different igui'es the same letters indicate identical parts.

Our improvements relate to a machine for scouring-setting, glossing, finishing, anddoing general tablework upon leather.

A represents the side-plate of the scouring apparatus, having in the top guides, A, working upon-ways, allowii'ig the machine to play freely back and forth at a proper height above the table. The plate B is pivoted to the side-plates A so as to permit it to oscillate with the reciprocating motion of the pitman C, operated by a crank. Pins upon the rods Gr control the extent of this oscillation. Below the points at which this plate B is pivotcd is a slot, D2, through the side-plates A, trou-gh which passes the head to a rod, D, passing between the plates A. A set-screw, D1, passing through a l g immediately above the slot D2, is attached to the head of the rod D, by which it may be raised or lowered.. llo the rod D are attached bow-formed springs, E, secured by stil-rups, E, below the rod. These springs, ex ending longitudinally, rest upon the crown of the jaws F, the

lshape of which is shown in fig. 2. These jaws are hinged upon rods, H, extending between the plates 4A. so as to allow them to play'vertically. The seconda :y jaws I are also hinged to the rod I-I, the hinge passing through ra slot left for this purpose in the middle of thi pipe-formed hinge of the jaw F. A screw, Il, passes through a hole in the lower part of the jaw F, in whic. it plays freely, and is attached to the top of the jaw I, so that while the jaw I may be allowed to play withou; moving the jaw F, the jaw F cannot be raised without carrying with it the jaw I. Inthe jaw I is secured a netallic scraper, being a sheet of metal of a suitable form, and attached by a set-scr`cw passing through the )wervpart of the jaw. In the upper jaw Fis attached, in like manner, the flat stone slickers F1, by set-screw passing through the upper jaw" F. The brushes K are attached in front of the two springs Kl, which are fastened to the bach part of the jaw F, on the pipe-formed hinge surrounding tho rod I'I, and curved upwards, so as to pass over the slickers. On each side of the upper part of the jaw F levers Gr are attached by stirrups' to the upper part of the jaw F, as'more clearly shown in iig. 3. The upper ends of the rods G are fastened to one end of the bell-crank It. This Crank is pivoted by a rod, M, running through its elbow, and pivoting the lever L` to the lugs Ml. Projections N, fig. 3, on the sides of the outside rubbers rest upon notches iu the sides of the .middle one, so that, while either of the outside rubbers may be raised by means of its lever, the lever attached to the middle rubber will raise all three of the rubbers at the saine time. No'tches in the plates Q, which are bolted to the upper plate' P, receive the upper arm of the lever L whcnthrown back, and, retaining it in place, hold the slicliers and brushes suspended when desired,v as shown by thc red lines in iig. 2. A hairhspring, Qig. 2, is attached to the top of the jaw F, and, passing through an opening-.left for thc purpose at ,the base of the jaw, Arests at the other end upon the upper face "of the jaw I, keeping the scraper thereof pressed upon the leather. Springs, R, are attached underthe guides on the plate A, and being carried down outside of the slickes, are attached to the cleaner S. 4The cleaner S passes in rear of the sli'ckers in thejaw F, and is, by tension of the springs R, pressed against them. When the plate D, with the motion of tliepit'mau, is raised, striking against the pins G1 in the rod G, it raises the brushes and sliclters, and the cleaner S being fixed in its position by the springslIt, it scrapes away whatever substances may have adhered to the slicliers, thus cleaning` them with every motion of the machine.

In operating this apparatus, .the leather to be workedfisfastened upon the upper surface of a table, so that the linishcr shall run forward and back with each revolution of the crank operating the pitman. By means of the set-screw Dl acting upon the -rod D, to which the springs E are attached, any pressure that may be desired can be brought to bear upon the sliclters. .The outside brushes and slickers may, by means of the levers L, be

Vsubstantially as and for the purpose set forth.

thrown up when desired, while working along the edges of the leather. Both ends of the finisher are made alike, and when the pitman is pushing or drawing towards either side, it alone is in contact with the leather, the other being raised by the plate B striking against the pins G1, as set forth.

Having fully explained our improvements, 'what we `claim as our invention, and seek to secure by Letters Patent, is-

1. The set-screws D and rod D, with the springs E, substantially as and for the purpose set forth.

2. We elairn the plate B, pivoted to the plates A, so as to communicate motion to. the rubbersccntrally, and without pressing upon the springs attached to the slickers.

3. In-combination with the platel B, we claim the rods Gr' and pins G1, for the purpose of raising the slickers and brushes when not in action, substantially as set forth. 4

4. We claim the jaws F and I, hinged substantially as set forth, in combination with the hair-spring I,

5. In combination with the jaws F, we claim the springs K1 and brushes K, substantially as set forth. 6. Ve claim the cleaner S, in combination with the slickers F1, operating'substantiallyas and for the purpose set forth.

7. We claim the lever L and notched plates O, or their equivalent, in combination with the rods G, attached 'to the jaw F, substantially as and for the purpose set forth.

8. We claim the arrangement ofthe points M1 so as to permit the raising of one or all of the rubbers, substantially in the manner and for the purpose set forth.

In testimony whereof we have lsigned our names to this specification in the presence of two subscribing lwitnesses.
